Question

I believe he area is incorrect. So can somebody help me to figure out the area and arc length. PLEASE show your work. So I can understand :)

Answer 1

To find the area of a sector, you must use the formula:
`a= (central angle)/(360) * \pi r ^(2)`, so, since we know the degree measure, which is 80, and the radius, 1.3, we plug it into the formula and get: 1.17984257435

To find the arc length, you must use the formula:
`(arc degree)/(360) * 2 \pi r`, then we plug in 80 as our arc degree and 1.3 as our radius, and we get: 1.81514242207
